[LLVMdev] Why some registered passes are not available through opt?
Dear LLVM, I'm trying to understand why opt tool does not know some of the registered passes, for example, -targetpassconfig, -gc-lowering, -unreachableblockelim, -unreachableblockelim, -stack-protector, -machinemoduleinfo. This prevents me from using bugpoint to reduce the crash in backend. As I understand, they should be registered and available through the command line in the same way as all other passes, shouldn't they? Thanks, - Dima.

Ciao, Duncan.

[LLVMdev] Why some registered passes are not available through opt?
Hi Duncan, Is it correct that opt does not understand codegen passes, but llc understands both analysis/transformation and codegen passes? I would like to modify bugpoint to work on this end.
